DJI O4 Air Unit

DJI O4 Air Unit Digital Transmission System

DJI engineered the O4 Air Unit to provide a high-performance, ultra-lightweight digital FPV solution for pilots who prioritize agility and minimalist builds. First and foremost, the unit weighs an incredible 8.2g, making it the lightest 4K digital transmitter in its class. Furthermore, the integrated 1/2-inch CMOS sensor captures crisp 4K/60fps video with vibrant clarity. As a result, builders of micro-whoops and 2-inch toothpicks can now record flagship-quality footage without the weight penalty of an external action camera.

In addition to its compact form factor, the O4 Air Unit delivers a robust and responsive flight experience. Specifically, the O4 transmission system provides a 1080p/100fps live feed with a stable range of up to 10km. Moreover, the new Racing Mode reduces transmission latency to just 20ms; consequently, it offers the near-instantaneous feedback required for high-speed technical maneuvering. Ultimately, the system features 23GB of internal storage, ensuring you can record your most daring flights even without a microSD card slot. Therefore, this unit represents the perfect balance of portability and high-definition performance for the next generation of micro FPV drones.

Key Features & Highlights

• 1/2-Inch CMOS Sensor: This hardware records high-bitrate 4K/60fps video; accordingly, it delivers professional-level detail in a fraction of the size of standard cameras.

• 8.2g Ultra-Lightweight Design: The miniaturized module fits into frames 2 inches and smaller; hence, it maintains the flight characteristics of even the smallest racing quads.

• 10km O4 Transmission Range: The system utilizes a single-antenna design for maximum weight savings; furthermore, it provides a reliable HD link in both open and obstructed areas.

• 20ms Low-Latency Racing Mode: This feature optimizes the signal for competitive flight; meanwhile, it supports up to eight simultaneous pilots without interference.

• 23GB Built-in Memory: The internal storage holds approximately 30 minutes of 4K footage; as a result, you never have to worry about managing external memory cards.

• RockSteady 3.0+ Stabilization: Integrated EIS algorithms smooth out high-frequency vibrations; consequently, your raw FPV clips look cinematic straight from the unit.

• Canvas Mode Support: The system fully integrates with Betaflight and iNav OSD; specifically, it allows you to customize your goggle display with real-time flight telemetry.

• Wide Voltage Input (3.7-13.2V): The unit supports 1S to 3S power configurations; therefore, it offers flexible installation options for a variety of micro and mini drone builds.
